Information recording method, information recording medium, and information recording apparatus

1. An information recording method using a recording medium having a first state by a first power level of an energy beam and a second state by a second power level of the energy beam which is higher than the first power level, comprising the steps of: when a period of a recording time generating clock in a recording mode is T, and a relative velocity of the energy beam and the recording medium is V, forming a sequence of the second state with a length avT (first mark), the first state with a length ivT (first space) following the first mark, the second state with a length mvT (second mark) following the first space, the first state with a length jvT (second space) following the second mark, and the second state with a length bvT (third mark) following the second space, as a first small recording pattern; forming a sequence which starts with the first state and ends with the first state while the first and the second states appear alternately a finite number of times, as a second small recording pattern; forming a state in which the second small recording pattern follows the first small recording pattern, as a basic recording pattern, the digital sum value of the basic recording pattern being zero; forming a state in which the basic recording patterns are repeated, as a recording pattern; forming the recording pattern which comprises the basic recording patterns obtained by changing a parameter j variously while parameters a, i and m are fixed, as a first recording pattern, the parameters a, i, m and j being natural numbers; forming the recording pattern which comprises the basic recording patterns obtained by changing the parameter i variously while parameters b, j and m are fixed, as a second recording pattern, the parameter b being a natural number; and measuring an edge position by using the first recording pattern and the second recording pattern.
